Conference paper


Behaviour of cable networks affected by geometric and physical nonlinearity combined, due to large displacements and cable slackening respectively, is investigated through a minimum principle on displacements. Relevant sign-constrained Non Linear Programming formulation, concerning algebraic or algebrized problems, is considered as the basis for numerical analyses. A significant example shows the successful match between the proposed approach and a suitable devised algorithm.
